accel/amdxdna: Fix potential NULL pointer dereference of abo->client
Closing a BO handle clears abo->client, while the underlying GEM object
may remain alive due to internal kernel references. As a result, code
executed after the BO handle is closed may dereference a NULL abo->client
pointer.
Remove accesses to abo->client from code paths that may execute after the
BO handle has been closed.
